Article Abstract

Cardiovascular diseases caused by atherosclerosis (AS) seriously endanger human health, which is closely related to vascular smooth muscle cell (VSMC) phenotypes. VSMC phenotypic transformation is marked by the alteration of phenotypic marker expression and cellular behaviour. Intriguingly, the mitochondrial metabolism and dynamics altered during VSMC phenotypic transformation. Firstly, this review combs VSMC mitochondrial metabolism in three aspects: mitochondrial ROS generation, mutated mitochondrial DNA (mtDNA) and calcium metabolism respectively. Secondly, we summarized the role of mitochondrial dynamics in regulating VSMC phenotypes. We further emphasized the association between mitochondria and cytoskelton via presenting cytoskeletal support during mitochondrial dynamics process, and discussed its impact on their respective dynamics. Finally, considering that both mitochondria and cytoskeleton are mechano-sensitive organelles, we demonstrated their direct and indirect interaction under extracellular mechanical stimuli through several mechano-sensitive signaling pathways. We additionally discussed related researches in other cell types in order to inspire deeper thinking and reasonable speculation of potential regulatory mechanism in VSMC phenotypic transformation.

Background And Aims: Neointimal hyperplasia is a key pathology in Type 2 Diabetes Mellitus (T2DM) vascular complications. It involves phenotypic switching of vascular smooth muscle cells (VSMCs) triggered by hyperglycemia, though the exact mechanisms remain unclear.

Methods: We employed Twist1 vascular smooth muscle-specific knockout mice with carotid artery ligation in a T2DM model to study Twist1's role in diabetic neointimal hyperplasia.

Background: Atherosclerosis is a chronic immune-inflammatory disorder in which vascular smooth muscle cell (VSMC) phenotypic modulation plays a critical role in plaque development and instability. Endoplasmic reticulum (ER) stress and its downstream effector, XBP1s, have been shown to influence VSMC behavior. During XBP1 mRNA splicing, a 26-nucleotide RNA fragment (X26nt) is excised, yet its biological significance remains poorly understood.

Advanced glycation end products (AGEs) have been associated with vascular pathologies including abdominal aortic aneurysms (AAAs), although their causal role remains unclear. In this study, we observed significant accumulation of AGEs in human AAAs, particularly in cases associated with intraluminal thrombus (ILT). , AGE exposure induced vascular smooth muscle cell (VSMC) migration and suppressed contractility, accompanied by reduced expression of contractile markers (α-SMA and MYH11) and elevated MMP-2.

Background: Thoracic aortic dissection (TAD) is a fatal cardiovascular disease characterized by vascular smooth muscle cell (VSMC) phenotypic remodeling and inflammation. Cannabinoid 1 (CB1/Cnr1) receptor has been implicated in cardiovascular diseases, but its role in TAD and its downstream signaling remains unclear. Genistein (Gen), an isoflavone abundant in legumes, has demonstrated promising therapeutic potential in cardiovascular diseases such as vascular calcification, hypertension, and atherosclerosis due to its anti-inflammatory, antioxidant, and metabolic regulatory properties.
